Victron energy Phoenix Inverter Smart 12 1600 230V Manual page 13

Relay on during normal operation. The relay will switch off once there is a low
battery warning. It will remain off in case the inverter shuts down due to low voltage,
and will only switch back on again once the inverter is operational and the battery
voltage is above the pre-alarm reset level. Use this option for load shedding, or to
automatically start a generator. Note that this can only be considered a poor-mans
generator start/stop. For more and better options, see here.
- External fan ("fan" in VictronConnect app)
Relay is off, unless the fan inside the inverter is running. Use this option to switch an
external fan, for situations when the inverter is in a small enclosed space.
- Disabled relay ("off" in VictronConnect app)
This option sets the relay in the OPEN position. Use this option if you do not plan to
use the relay function.
